To all whom it may concern:

Be it known that I, \VILLIAM L. ROSE, a citizen of the United States, residing at Chicago, in. the county of Cook and State of Illinois, have invented certain new and useful Improvements in Steam-Generating Apparatus, of which the following is a specification.

My invention is concerned with certain new and useful improvements in apparatus for generating steam, and is designed to produce a device of the class described by which a uniform supply of superheated steam will be delivered for any purpose desired without any attention on the part of the operator, once the apparatus is in operation.

In carrying out my invention, I have devised a number of novel features and combinations, as will be fully described in the following specification and particularly pointed out in the claims.

To illustrate my invention, I annex hereto seven sheets of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which,

Figure 1 is a perspective view of one end of the apparatus; Fig. 2 is a perspective view of the other end of the apparatus, the combined mechanisms of Figs. 1 and 2, representing the complete apparatus with the parts separated and extended so as to show their connections, rather than their relative positions, which may be varied as may be necessary for the different locations in which they are to be employed; Fig. 3 is a central longitudinal section through one of the boiler sections embodying my invention, the division plates, however, being shown in elevation; Fig is a vertical section of the same on the line A-A of Fig. 3; Fig. 5 is a horizontal section on the line BB of Fig. 3; Fig. 6 is a horizontal section on the line CC of Fig.10, showing how the oil generator sections are preferably connected up where a plurality of boilers are associated together; Fig. 7 is a perspective view of the boiler section shown in Fig. 1; Fig. 8 is a side elevation of one of the separating plates removed from the boiler; Fig. 9 is a top plan view of a series of boilers coupled up as they will be when a large capacity for steam is required; Fig. 10 is a central longitudinal sec tion through a modified form of a boiler section containing my invention; Fig. 11 is a horizontal section on the line DD of Fig. 10; Fig. 12 is an enlarged longitudinal vertical section through one end of the vapor generating portion of the boiler showing the mechanism for cleaning the same; Fig. 13 is a side elevation of one of the separating plates used in the vapor generator; Fig. 14 is a perspective view of one end of the modified form of boiler section shown in Fig. 10; Fig. 15 is a perspective view of still another modification of the boiler sections, with a portion of the outer casing broken away to show the interior arrangement of the parts.

One of the main features of my invention is a new and improved boiler section, by which water admitted at one end is quickly converted to steam and passed through a mass of heated metal so that it is delivered entirely dry and strongly superheated;.and the particular construction in which my invention is embodied is designed to produce a device of the class described which shall be automatic in its operation and most effective in performing its functions; which shall be economical as regards fuel consumption; free from joints exposed to the fire; which can be readily cleaned; and which while having all these desirable features is at the same time simple in its construction, cheap to manufacture, and withal durable.

Before proceeding with the description of the complete apparatus, I will first describe the details of my novel boiler sections, as shown in detail in Figs. 3 to 15.

The essential feature of my improved boiler section, common to all the forms herein shown and described, is a single hollow shell, preferably cast, and preferably in the form of an elongated rectangle, in which are placed a series of division plates which permit the water and steam to pass them at their alternate ends, so that it passes through a tortuous and extremely elongated passage which is filled with metal chips, so that the water, which is quickly converted into steam upon its entry, passes in the form of steam through a large mass of highly heated metal, so that when the steam emerges, it is absolutely dry and highly superheated.

Referring first to the particular form shown in Figs. 3 to 9, the sides 20 and 21, top 22, bottom 23 and end 24 are all cast from a single piece of metal, and are preferably of about the proportions shown in the drawings, the sections being high enough to utilize all the heat of the fire, and narrow enough to permit the interior filling being highly heated throughout. The end 25 is secured to the body of the casting by any suitable means, such as the cap screws 26, which will be out of the fire, which is preferably applied to the bottom of the boiler. When the section is being manufactured, a layer of metal chips 27 is placed next to the end 24 after the metal gauzes 28 have been placed in position over the opening for the clean out pipe 29 and the steam outlet pipe 30. These chips are preferably of copper. One of the division plates 31 is then placed upon the layer of metal chips, and a second 'layer of the chips is then put on, which in turn is covered by another division plate 31, which, however, has the end having the cut away portion 32 at the opposite end of the boiler. In this manner, the boiler is completely filled, after which the end 25 is secured in place after the metal gauze 28 has been put in position over the apertures for the water in the pipe 33 and the clean out pipe 34. Of course it will be understood that the gauzes 28 are employed to prevent the metal chips from escaping into the pipes.

Vith this construction, it will be seen that water which is admitted through the pipe 33,

is forced to travel down to the bottom past the first division plate; up to the top where it passes the second division plate; down to the bottom where it passes the third division plate; and so 011 until the other end of the boiler is reached. Of course the water is converted to steam long before the discharge end of the boiler is reached, the distance it traverses before it is changed to steam depending of course on the heat of the fire. After it is converted to steam, the steam continues through the same passage, and necessarily becomes highly superheated before it is discharged from the pipe 30. By means of this extremely tortuous passage way thus formed, it will be apparent that by using a single section or boiler, steam, as dry and superheated as may be desired, can be obtained; and when a large quantity of steam is desired, all that is necessary is to couple up a plurality of these sections, as shown in Fig. 6, by means of the bolts 35 passing through the ears 36 formed in the tops and bottoms or ends thereof.

All the steam outlet pipes 30 may be connected by the unions 37 to a common steam supply pipe 39, each steam outlet pipe 30 being preferably provided with a pet cock 38 by which the quality and dryness of the steam supplied by each section may be tested, so that in case of any failure of operation, the fault may be located. Of course the water supply pipes 34 are similarly connected to a common water supply pipe, as shown in Fig. 1, which will hereinafter be more fully described. To facilitate the assembling of these boiler sections, and at the same time to leave channels or flues 40 between them through which the heat will ascend, I provide the flanges 41 which a1ter= nate on opposite sides thereof, as clearly shown, and serve to furnish the fiues desired as well as to strengthen the boilers. These ribs also operate as heat collecting flanges, and may be of the zigzag shape as shown in Fig. 14, and as many or few of them as may be desired for this purpose can be employed.

By means of-the clean out pipes 29 and 34, both being preferably provided with cocks 42, I can quickly flush the entire boiler and wash out such sediment as may accumulate without disturbing the pipe connections. Or if it becomes very foul, it is possible to remove the end 25 and the division plates and metallic chippings so that they can be washed separately.

In Figs. 10 to 14 I have shown a preferred construction in which the division plates 31 are formed integral with the casting by means of cores, and the end 25 is also formed integral therewith. Vith this form, the plugs 43 have to be employed to close the core holes, and the holes used to fill the casting with the metal chippings 27. This construction has the advantage over the one previously described in that it is simpler and dispenses with the joint at the end which is necessary in the other construction described, and the division plates formed integrally with the casting serve the additional purpose of strenghtening it by tying it together inside at frequent intervals, as well as transmitting the heat from the surface of the casting throughout the metal chips. Vith this form, I preferably extend the ends 24 and 25 below the bottom and have the ears 36 projecting outwardly therefrom so that even the bolts 35 will be entirely out of the flame, the lower flanges providing a fire front and preventing the fire from the burner from reaching the outside of the boiler.

In Fig. 15, I show still another construction which has features in common with both of the previously described constructions. In this form the end 25 is also integral with the main casting, but is enlarged, as shown, and provided with the aperture 44 at its upper end through which the division plates 31 similar to the division plates 31 are introduced one at a time, and separated by the metal chippings 27 as in the other constructions. The ends having the recesses 32 are arranged alternately for the same purpose, and when the boiler is built, the aperture 44 is closed by a plu not shown in the drawings.

In Figs. 1 and 2, I have shown my improved boiler sections and Vaporizers connected with the various other mechanisms necessary to make a complete steam generating outfit. Referring first to Fig. 1, I have shown three boiler sections, preferably of the specific form shown in Fig. 10, assembled as shown in Fig. 9, and having on one side the feed water heater and purifying section 57, which is similar to the steam generating sections except that the division plates 31 employed therein to form the tortuous passage are fewer in number, and the metal chippings are omitted. The outer side thereof is closed by the plates 58 secured to the main casting in any suitable manner as by the cap screws 59, so that they can be readily removed for cleaning out the scale and sediment that is deposited therein. The general design of this section 57 is symmetrical with the design of the central boiler section, except that it extends farther down, in fact as far down as the end plates, so as to form a chamber or recess in which the burner is mounted. On the other side from the feed water heater section is the exhauststeam heating and muflling section 60, which is similar to the section 57, except that it does not need to have the removable plates 58, and its lower portion extending below the bottoms of. the central boiler sections likewise serves as one side of the chamber in which the burner is located. Both of these sections 57 and 60 are provided with the blow ofl cocks 61 for cleaning out the sections.

The water pipe 62, which leads from the closed water tank 63 (to be more fully described hereinafter), opens into the feed water heater section 57 preferably at the upper rear end thereof, and the water in passing through the tortuous channel of the feed water heater 57 becomes highly heated and emerges from the pipe 64, which is connected to-the water supply head 65, and has the regulating valve 66 interposed, which is of any ordinary construction, and serves to automatically reduce the amount of water that can pass it as the pressure of the water thereon increases, thereby preventing any possibility of the boiler being flooded as a result of any undue pressure in the closed water tank 63, or diminution of pressure in the boiler. The water in the pipes 83 for each of the boiler sections is connected to this head 65, and the valves 66 are interposed in said connections in order to enable me to throw the sections into or out of opera tion as may be desired, or to independently control the quantity of water supplied to each section. The water being thus admitted to the boiler sections passes there through in the manner previously described and emerges through the pipes 30 which are connected to the steam supplv head 39 in the manner previously described, and the steam supply is carried thence by the steam pipe 67 to the engine 68, which may be of any desired type, or to any other place where its use is required. A steam relief Valve 69 is placed in the pipe 67 and in case the pressure becomes too strong in the head 39,

the steam is blown off tln'ough the pipe 70 into the chimney 71 which is placed with the hood 72 over the feed water heating, boiler, and exhaust'steam super-heating and muflling sections, in the manner clearly shown in Fig. l.
